Fundamental research: looks at the world at large and tries to generate new ideas or explanation about how the world works and why; may not have application in everyday life in the immediate sense.
Applied research: seeks to solve a specific societal problem or uncover more information about a particular issue; has direct implications in practice.
Narrowing the Research Topic
Two features of a broader topic can lead to the research question: the constructs and the population of interest.
Construct: a concept that is possible to measure in a form.
The population of interest: group of subject that share simialr charateristics or tied in a similar context that researcher have interested in
Operationalization of Constructions
Operationalization is nothing more than our ability to transform constructs into measurement pieces. The best researcher is able to measrue all the characteristics of a construct.
Operationalization: turning constructs into actual variables to measure
Variable: a specific feature or aspect of the construct that can take different values for each participant in a study.
Conceptualization: the process of breaking down constructs into smaller pieces and clarifying to know the precise meaning of each.
Types of Variables: Collecting Information
Independent and Dependent Variables
Independent variable: the explanatory or predicting variable that explains the variation in the dependent variable; often constant/doesn’t change for the participant
Dependent variable: the outcome; what researchers want to find out from a study and what they hope is influenced by the independent variable.
Variables are unique to each study; a variable can be dependent in one study and independent in another.
Control Variables
Control variables: any variables that are used to control the results; not directly related to the focus of the study but crucial for understanding the relationship between the variables of focus.
They help minimize biases and provide more accurate findings.
Confounding and Disturbance Variables
Confounding variables: influence the independent variable in such a way that the results from the dependent variable become untrustworthy; could not have been controlled or predicted during the study’s design; only become apparent during data collection or analysis.
Disturbance variable: lurks in the background and disturbs the findings of the dependent variable; common characteristics of participants mislead the findings of the study without the researchers’ awareness.
Moderators and Mediators
Moderators: variables that can strengthen or weaken an already established relationship between the independent and dependent variables.
Mediators: intervening variables that interfere with the relationship between the main variables; when a mediator is present, the relationship between the independent and dependent variables may not even exist anymore.
Types of Hypotheses
Hypothesis: a statement that predicts a specific phenomenon or behavior.
They are usually present in a quantitative study but not a qualitative one.
Alternative Hypothesis and Null Hypothesis
Alternative hypothesis: the prediction based on literature and theory about what the testing results will be; that is, what the variables are expected to look like once the data is collected.
Null hypothesis: claims there is no relationship between the variables of interest in the study; this is the hypothesis researchers are actually testing with their findings.
Research outcomes have two options: reject the null hypothesis in favor of the alternative hypothesis, or fail to reject the null hypothesis.
Directional Hypothesis and Nondirectional Hypothesis
Directional hypothesis: predicts a specific course for the variables
Nondirectional hypothesis: has no direction and simply predicts a relationship between two or more variables; rather than making assumptions on how the variables will behaving, researchers are investigating the possible relationship between variables.
Open-Ended Question
For qualitative studies rather than quantitative; that is, when the researcher has many constructs but is not attempting to measure them
A qualitative study asks different types of research questions and has a different methodology to collect data.

Discussion
A researcher is focused on how sleep (measured in hours) influences academic performance (measured in GPA).
A researcher wants to find whether academic performance (measured in GPA) influences self-esteem (measured on a 1 to 10 scale).
A researcher is studying the influence of television watching (measured in hours) on speech onset of toddlers (measured in number of words spoken by age of 2).
A researcher is attempting to see whether self-esteem (measured on a scale of 1 to 10) relates to and/or influences substance abuse (measured in frequency of substance use and abuse) among adolescents.
A researcher is interested in understanding whether exposure to a large variety of food (measured in the number of different food textures and food types) influences the level of pickiness among children younger than 6 years old (measured on a scale of 1 to 10).
Find the dependent and the independent variables in these examples:
What is the difference between the null and alternative hypotheses?
What is the purpose of the null hypothesis?
How can we distinguish between disturbance and confounding variables? Illustrate with an example.
What are some ways to operationalize constructs, such as sleep, time, and anxiety?
What is the purpose of having a direction when we design an alternative hypothesis?
What do directional and nondirectional hypotheses tell us?
Summary
This chapter introduced the concepts of fundamental and applied research. We consider fundamental research those broad theories that attempt to explain how life works and can be applied to many different things rather than one specific problem.
Terms
Alternative hypothesis: the hypothesis that attempts to predict how the variables will relate to each other after the data are collected.
Applied research: research that seeks to solve a specific societal problem or uncover more information about a particular issue.
Conceptualization: the process of breaking a construct into smaller pieces and clarifying its specific meaning in our study.
Confounding (intervening) variable: variable that influences that independent variable in a way that causes results from the dependent variable to become untrustworthy.
Construct: an abstract term that is difficult to measure and can be understood differently by different people.
Control variable: variable that minimizes biases and provides more accurate findings by removing characteristics that could affect the relationship between the independent and dependent variables.
Dependent variable: the outcome or surprise variable that is influenced by the independent variable.
Directional hypothesis: a hypothesis that predicts a specific course for variables.
Disturbance (extraneous) variable: variable that can disturb the findings of the dependent variable, which cannot be controlled.
Fundamental research: by collecting information about large groups of people, research that tries to generate new ideas about how the world works and why.
Hypothesis: a statement that predicts a specific phenomenon or behavior.
Independent variable: the explanatory or predicting variable that explains the variation in the dependent variable.
Mediator: a variable that interferes with the relationship between the independent and dependent variables to the point where the relationship may be destroyed altogether.
Moderator: a variable that can strengthen or weaken an established relationship between the independent and dependent variables.
Nondirectional hypothesis: a hypothesis that has no direction, but predicts a relationship between two or more variables.
Null hypothesis: a hypothesis that claims there is no relationship between the variables of interest in a study.
Operationalization: the process of turning constructs into measurable variables.
Variable: measures a specific feature or aspect of a construct and can take different values.
